In the drawings, in which like parts are denoted by the same reference characters throughout the several views,

Fig. 1 is a fragmentary vertical section of a can mill showing the improved distance and bearing plate in accordance with the present invention as in place, and

Fig. 2 is a similar View showing the plate removed and the top roll bearing shifted sidewise.

Referring more particularly to the drawings, I0 designates generally the mill housing, II one of the top roll journals` and I2 the top roll bearing therefor.

In accordance with the Munson patent this top roll bearing is made with a short lip I3 at one side and a long lip I4 at the other side.

6 Clainis'l (Cl. 308-9) n The top cap is indicated at I5, the ram at I6Y and the pressure plate at Il, these parts being removable in the usual manner from the mill housing. a g

:In accordance with the present inventionfa fillerV plate I8 occupies a space provided therefor in the mill housing alongside thev long l-lip I4 of the top roll bearing I2. Thisfiller plate I3 serves as a distance piece and alsojasa bearing plate. It may be held removably inthe housing injany appropriate manner. Asshowmits lower edge is adapted to slidably fit intor a recess l|59 formed in the mill housing below the space which such plate is adapted to occupy.` This recess I9 is shouldered on the sideV adjacentthe journal II soas to retain the ,plate in proper position at its lower edge when the upper portion of such plate is affixed by the screws 20 tothe mill housing. Suchscrews pass through countersunk holes 2| in the upper portion of the plate I8 and into threaded sockets 22 in the mill housing. A

The upper edge of the plate I8 is provided with one or more tapped sockets 23 to removably receive the lower threaded studs or ends 25 of lifting rods 24.

nIn thenuse of the invention, the leftlonger lip ldoverlaps the cylindrical journal II Vby' .a distance O. The thicknessvof the plate l8 and thespace in theV mill housing occupied .bylsuch plate is somewhat greater than this overlap .0.

Fig. A1 shows the assembled Vposition of the parts in which the plate I8-isin eecta .side 'wallcf the mill housing I D.V In this .capacity it forms an distance piece which accurately. holds the top roll bearing I2 tothe contour ofthe top roll journalII. y Y

"flfhe arrangement will permit the removal of the' toproll bearingIZ witheuttl-ienecessity of removing the top roll, both top caps with rams and both pressure plates. If the bearing in the left hand housing, for instance, of the mill runs hot it may be removed Without disturbing the parts in the right hand housing and Without disturbing the top wall itself. To remove the hot bearing, the left hand top cap I5 with its ram I6 and pertaining pressure plate I'I over the affected top roll journal are all removed. Thereafter the screws 2% which are now accessible are withdrawn and the screw lifting rod 24 is lowered and has its end 25 engaged in one of the tapped sockets 23, or two or more of such lifting rods 24 are so engaged with the plate I8.

out in the manner indicated in Fig. 2. The removal of the plate creates a space or opening of a greater width than the overlap O laterally of the top roll bearing I2 into which this bearing may be moved by a sidewise and upward motion until the overlap O no longer impedes the lifting out of the bearing. The replacement of the bearing takes place in the reverse order. A

Such procedure will obviate the necessity of removing any of the parts as the top cap and ram with pressure plate on the right hand housing and the top roll shaft will at all times remain in position.

It will therefore be obvious that the improved arrangement results in considerable saving of time which is a very essential factor in the cane mill on the continued operation of which depends the economy of production and the uninterrupted operation of the other departments of manufacture in the sugar factory.

The plate i8, besides serving as a distance plate for the removal of the top roll bearing I2, has another useful purpose, that is of serving as a pressure plate, and for this purpose it is preferably made of a metal suitable to reduce fric` tion between the plate I8 and the top roll bearing l2. In case of wear, the plate I8 can be easily and conveniently replaced.

Although I have described and illustrated herein the best form of the invention known to me at this time, it will be understood that the application exhibits only one mechanical embodiment of which the invention is susceptible and I reserve the right to all such modiiications and changes as may come within the scope of the following claims.

I claim:

l. For use with a cane mill housing having therein a vertical recess adapted to receive and support a top roll journal the combination with said mill housing and journal of a top roll bearing having at one side a short lip and at the other side a long lip, said long lip adapted to extend down below the horizontal center line of the roll journal and having a part overlapping said journal, the width of said bearing being less than the width of said vertical recess thereby defining a space between said bearing and said mill housing adjacent the long lip, and a ller plate removably received in said space, the length of said plate and the depth of said space being greater than the length of said long lip whereby said filler plate overlaps the long lip of said bearing.

2. The combination of claim 1 characterized by the fact that fastening means is provided to secure said filler plate to said mill housing.

3. The combination of claim 1 characterized by the fact that an area in said vertical recess lying above said journal and bearing denes an open space through the top of the mill housing to permit the upward withdrawal of said ller plate and the subsequent upward withdrawal of the bearing after said bearing has been slid laterally into the space previously occupied by the removed lller plate thereby enabling the long lip portion of said bearing to clear the journal.

4; The combination of claim 1 characterized by the fact that 'said iiller plate is constructed and arranged to receive a lifting means by which the same may be lifted out of its space in the vertical recess of said mill housing.

5. In a cane mill a housing having a lateral vertical recess therein for receiving a roll journal, the combination with said roll journal of a removable top roll bearing having a long lip parallel to and disposed adjacent but removed from a wall of said lateral recess in said mill housing, a filler plate removably mounted in said recess and lying between the wall thereof being spaced from but proximate to said long lip of said bearing, the area between the wall of said vertical recess and said long lip defining a space the depth of which is greater than the length of said long lip for receiving the lower edge of said ller plate, and a removable fastening for holding the upper portion of said plate rigidly to said housing. 6. In a cane mill having a top roll journal, a top roll bearing therefor having short and long lips with the long lip adapted to extend below the horizontal diameter of the journal with a portion of said lip adapted to overlap the journal below the horizontal diameter of said journal, a mill housing having an open-ended recess for receiving the journal and its top roll bearing, said recess being wider than the top roll bearing to 'permit the top roll bearing to move relatively down upon said journal with the long lip clearing the horizontal diameter of said journal and thereupon to move laterally in the recess to cause the top roll bearing to conform to the journal with the inner lower part of the long lip overlying the journal below its horizontal diameter Whereby a space is left in the recess outwardly of the longer lip, and a distance and bearing plate removably mounted in said space substantially filling said space to prevent lateral backing oi of the longer lip from said journal.
